Yup and basically less/same price to that of a 200Ah lead acid, yet this will give better performance. Isn't that a good deal

Link to the seller pls.

How much is the 12v 100ah going for?

ceaser:
Fret not.

What he means is "good dangerous" rather than "dangerous dangerous" or "bad dangerous"

He simply means that you get carried away by the sustained voltage over a long time despite load that you won't border to even check out the voltage again. At that point, you may miss when the voltage starts to drop on the meter.

With Lead chemistry, once you put a big load on it, the battery drops by 1volt or less. Then the volt drop with use and time is a linear relationship. However in the case of LFP(compared with Lead for capacity for voltage), if the battery was fully charged to 13.3v (for a 12v LFP battery), you won't really notice the drop in voltage and it can remain at that 13.3v for several hours before you notice any drop. That's the characteristic discharge curve of lithium.

Having said that, the BMS will do justice to ensure you don't overdischarge your battery.

@ Adrusa. I hope to take delivery of an extra 12v 100ah LFP tomorrow. I needed 120ah but 100ah was the last samurai that I was lucky to meet left. Damn, he was even sold out on 24v and 48v.

mctfopt:
They've already doing that. I doubt CBN does any regulation any more, it is now all men to themselves

Try gtb. I use gtb

OK, the 26" version of the DC TV is around 30k but if you bargain well, you could get it for 28-29k.

Make(r) of the tv?

eleojo23:
Shopping on AliExpress is a gamble right now due to the Corona thingy.

I suggest you contact one of these sellers on Jiji. Type "DC plug" in the search bar.

If you still want to use AliExpress, type the same in the search bar. I can't post links for now because I'm on parole from the last antispam bot sentence. I don't want to go back to NL jail.

I already bought some dc plugs for my fan so I will check if mouth is same and use one of them for the decoder. I will have to scrimp and get a small dc tv.
Iv been off grid for 11 months now due to spoilt transformer so i am trying all avenues to minimize consumption before i upgrade my system

ceaser:
@Topmost11, that second picture by eleojo23 will be perfect for you if you don't wanna go thru the hassles of soldering or twisting of wires together. It's plug-and-play.

but unfortunately not long enough. Well as a diy enthusiast, iv bougth a meter and have soldering iron. Im about purchasing something called a spot welder too.

eleojo23:
I use this DC plug (first picture). Got them from AliExpress but it's available on Jiji for as low as N500 for a pack of 10 pieces. The second picture is also an option.

Puchase link on aliexpress pls

I understand you perfectly. And thats what i mean. Discard/eliminate the adapter. I was just showing the adapter.
Connect 12vdc to 220 vac adapter? Lol

So now i can use my decoder without inverter. Why didnt i buy dc tv the time i bought my tv? Any way i can adapt my tv too? There should be a way the decoder can be connected to my laptop to perform tv function. I cant afford buying a dc tv now

ceaser:
I don't mean connecting the DC source to the GOTV adapter o. What I mean is that the same power-in port for the adapter on the decoder is the same place you'll plug in your 12v direct DC source. In fact by the time you are through with direct DC connection of the GOTV, you won't be needing that AC power pack (adapter) that comes with it, except of course you decide to cut off the DC plug end of the adapter to use for the direct DC connection. But I would advice it's better you get your own DC plug and solder in your wires to connect to the 12vdc source.

Correct me if i am wrong. The decoder is wired for dc operation. So the what happens is this: the followcome power cord converts ac to dc. Hence why the power cord is not an ordinary plug but a laptop charger type. That is why you were able to connect dc plug to it directly. Mine says output is 12v, 1.5a.

ceaser:
The GOTV decoders have external power pack (adapter). The ratings on it is usually 12vdc 1amp. So you just need to DIY a 5.5mm X 2.5mm DC plug that goes into the same input port for the adapter, then appropriately connect the positive and negative terminals to the battery. The decoder still works well on voltages as low as 9vdc.

Those old, big DSTV decoders have their power pack in-built, so it may be a bit of a challenge to have them run on DC volt direct.

There was a time the UPS in the picture powers a GOTV decoder and 14 inches portable TV/DVD for 3½ hours.

Price and source pls. And will the fan charge it or I need to get new charger?

ceaser:
Bro, except you're using Lithium chemistry batteries, 7ah lead acid batteries will not serve you overnight with all these rechargeable fans dem.

4ah 12v cane with one QASA rechargeable like that and the battery works for only 4hrs after full charge, gave up the ghost on the 3rd month of use. I changed to it an external 7ah 12v thinking I'll get super long working time but battery also died on the 4th month.

Changed things to Lithium 12v 5ah (2,200mah in 3s2p config) and I've had peace ever since.

dejidotun2000:
I can't see from your picture whether the longer leg connects to the inner or outer terminal.

The outer terminal is negative and the inner terminal is positive. So if the outer terminal is the one that connects to the longer leg then the longer leg is the negative and vice versa.

Longer leg to outer terminal. Thanks

Correct polarity will be:
red =+ve, black =-ve and
long leg -ve, short leg +ve.
Am I correct?.

Experts.
One of my fans is faulty. All is working except the blades. By all I mean it is charging the battery if I switch it on, led bulbs are working except the blades are not rolling. I disconnected and removed the complete head(blade and motor) and replaced it with another and it worked fine.

I had extended the battery terminals to be able to use a bigger battery.
Problem started(I am told, I wasn't home) when my son changed the fan's position. I guess he connected wrong polarity. When I opened the motor, it seems a tiny spider ic is burnt(its surface looks rough compared to others) but I am not too sure. Can all these coil rewinders fix the fault? I have a customer that repairs ac fans but I'm not sure if he will be able to do this. He once told me spider ic's are not replaceable.

eleojo23:
I think what he means is ensure you connect positive to positive and negative to negative.

So I thought too. But I had to ask to be sure.

Explain this reverse polarity pls. Fan port says 12-15v in. So I guess it will take my 12v panels. If 7ah battery serves me overnight, 40ah should serve 3 fans(7ah×3=21ah)overnight and leave for day use when/if necessary.
I am still weighing my options and seeking opinions.

unicmarket:
Ensure your solar panel dc voltage is same range with the required input voltage of the fan.

So ensure you connect without mistake ( reverse polarity) that’s when you are connecting to the fan dc port, the fan it’s self as a dc cc to charge the battery, if you connect the panel to the battery directly you will risk over charging the battery.

Ensure the panel is same dc range for the fan.

zeanslim:
Direct DC, there will be more power loss if used via inverter.

Your fan is non rechargeable dc fan. But for my fan, Is the direct DC via the DC port or battery terminals?

For those who followed my queries. How do I connect 80-100 panel to the fan?
It is rechargeable ac/fc fan with solar charging port.
Should I use a charge controller and drop in via the battery terminals or connect the panels directly to the fan via the charging port( would it have its inbuilt charge controller? Its battery is 4.5ah but I have rigged it with 7ah and is working fine. Will it go 20ah?

Dam5reey:
Perfect example of what I expect from this thread, how on Earth will someone say 20watts panels is good to run 40 watts device 247 are you truthbetold?

For optimization, Correct sizing matters, the statement in bold is very accurate don't need to ask questions I just believe it, cost its practical.

600watts panels to effectively charger 200AH battery Rule..

I also thought 20watts panel is too small. But I don't need 24/7 fan. Only as need arises which can't be more than 10hrs daily.

Dam5reey:
Seller only want to make sales does not care about quality.
Even 5W panel will do

Solar may not be cheap, but worth it on a long run.

I started small as well, 80watts panel, 18Ah battery, 15Watts Yingli solar fan, 2 DC 5W 150LM bulb that only consume 2.5watta each. After real life experience, then I was able to deduce, how Solar set up actually works..

He has given you expo, just copy and paste the formula.

Maybe i should give the explanation.
My panels and battery gives me light(and TV) 24/7. Inverter is switched off overnight(since we don't need it) and comes back on 5:00 to 7:00 and is then switched off on way out to work in the morning until afternoon. So if I deplete the fan battery overnight, I want it fully charged by the time I get back from work. But inverter cant do that because it is off, hence my dilemma.

So I need independent panel to charge the fan(3) batteries OR wire direct from inverter battery to all fan battery terminals, thereby eliminate/remove completely the fan batteries.

dejavus:
Hi Guys,

Any RELIABLE Panels/Inverter seller on here, without having to triple and quadruped checking anything. I am saying this because I have been sold fake/re-badged panels on here few years ago and the seller swore by everything but later admitted and put it down to their supplier's fault...Yeah right.

So any RELIABLE sellers please let me know.

thanks in advance.

I have said before. Let me buy inferior and be sure it is inferior than buy fake "original".

ewizard1:
What spec are you asking ? Quantity?

Depends on price.

Anyone selling lithium ion battery, 3.7v 18650? Pls state price. Thanks

zeanslim:
I have something similar like this, it never goes of ..like the fan is running forever 24-7.

I use a 40ah battery, and 150 watt panels and a 30amp chinko charge controller.

With a QASA solar standing fan 24watts(highest speed), I use it for 24-7 never off.. it also power some other stuffs like Laptop and phone charging ( extra 30 watts - when needed)

It have never gone below 12.6-12.7 volt and the battery gets fully charge before 12pm-1pm (even in cloudy or raining weather.

The fan is 40 watts boscon. Seller says 20watts panel is ok to charge it. Though I am thinking of 14ah-20ah battery and 40-60watts panel.
Pls advise o.



Come to think of it. Why stress myself. Why not just run wire to the rooms from the inverter battery terminals and connect to the battery terminals of the fans. With that I won't need to replace fan battery.

What I did presently is to get 7ah battery and loop to the fan battery port. Only problem is fan can't charge it until inverter is on. I need a system that will charge the fan batteries during sunhours independent of the inverter. Thus whether we are home or not and pit inverter on, solar is charging the fan batteries.

24watts rechargeable standing fan? Where were you when i was looking for low wattage fan to buy? could you snap the label on the fan? I would like to see the specs of the fan.

harizonal123:
What your battery make?

If I am not mistaken, he said qasa

The follow come battery is 12v 4.5ah and consumes 40watts. I have replaced the battery with 7ah by extending/passing wire externally to the battery. Now I want to dedicate a panel to it. What size of panel should I get? Thanks

How/with what do I connect the panel to the fan solar port. What is the name and where do I get it. The small panels I have used come with crocodile clips.

Is anyone selling battery of 40ah here? How much? Thanks.

What solar panel will charge a 40watts rechargeable standing fan if it gets to 30% dod daily

Hmnn. Christian sex!
I guess the writer meant how a christian should have sex. As long as it is within matrimony, "anything" goes but on condition that it does not violate the bible. I have not seen where the bible talks about how to have sex. The bible only says "knew her" when sex is within matrimony and "laid with her" when sex is outside matrimony. So missionary,doggy, scissors, cowgirl etc is not in the bible. This means we are not told how to have sex. Pleasure yourselves however you like so far as it doesn't negate the dictates of the bible and it doesn't go against societal common sense. For example, because I am married, do I now go into the market with my wife and engage in sexual act? That negates societal common sense. Also, do I say we are married and I am not satisfied with one round my wife can accommodate, I should now do 3some? Or do anal with another woman and say i did not have sex with her? Sex "tools" is the penis and vagina, not penis, vagina and anus.
Which brings us to MouthAction. Should my wife suck my dick or should I lick/finger her vagina? I think it is allowed so far as you derive pleasure and is mutually agreed.
Then a wise individual may day what if anal is mutually agreed with my wife, can't we do it?

So it all boils down to do what is not against the bible. Where you are not sure of what the bible says on a particular subject, just don't do. In the end you will not be at fault.


That's my two pence.

Hmmn. All this going forth and back, (or is it back and forth) over energy usage tire me o. I don't blame una sha. Na AE I blame. If to say you no get light to power your ac, fa, fridge etc, and the heat bilala you well well like person wey corona virus catch, una no go get mouth to dey yab each other/one another.

On a more serious note, pls sheat your swords and rest this issue. We are all adults and let us behave as such.
Thanks all

solasola:
That cost less than 6k for new in ALABA. I advice you should just go for the 1000w with charger. Cost 15-20 in alaba . the choice is yours.

Any seller there you can recommend sir?
